   To enable scaling of existing transport systems to ultra high data
   rates of 1 Tbps and beyond, next generation systems providing super-
   channel switching capability are currently being developed. To allow
   efficient allocation of optical spectral bandwidth for such high bit
   rate systems, International Telecommunication Union
   Telecommunication Standardization Sector (ITU-T) is extending the
   G.694.1 grid standard (termed &quot;Fixed-Grid&quot;) to include flexible grid
   (termed &quot;Flex-Grid&quot;) support (draft revised ITU-T G.694.1, revision
   1.4, Oct 2011). This necessitates definition of new label format for
   the Flex-Grid. This document defines a super-channel label as a
   Super-Channel Identifier and an associated list of 12.5 GHz slices
   representing the optical spectrum of the super-channel. The label
   information can be encoded using a fixed length or variable length
   format. This label format can be used in GMPLS signaling and routing
   protocol to establish super-channel based optical label switched
   paths (LSPs).
